IMPROVEMENT IN GUIDES FQR SEWING-MACHINES.

Specification forming part of Letters Patent No. 40,464, dated November 3, 1863.

10 all whom it may concern:

Be it knownfthat 1, WARREN L.'FIsH,.of Newark, in the co'unty of Essex and State 0'. New Jersey, have invented a new and useful Improvement in Sewing-Machine Guides; and

I do hereby declare that the following'is a full, clear, and exact description of the same, reference being bad to the accompanying drawings, forming a part of this specification, in which-'- Figurel is aright-hand-side View of a guide having its parts arranged for what is known as the Wheeler & Wilson sewing-machine. Fig. '2 is a left-hand-side view 'of'the same. I Fig. 3 is a plan of the'same. Fig. 4 is a front View ofthe same.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to the attachment toa sewing-machine guide of a roller having a smooth periphery composed of indie-rubber, or other gum or soft material of a similar nature, of sufficient length to press the whole width of a a tuck, hem, or plait for the purpose ot'keeping 'lo'enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

a 1s a long narrow flat plate, which may be termed thei base-plate of the guide, and c is another flat plate, arranged above the said plate a, and united therewith at one end, as shown at c in Figs. 2 and 3, in such manner as to leave a space between the two for the passage of the cloth of about one-sixteenth of an inch in depth, the length of the said space from the point where their junction commences to the opposite ends of the plates being equal to the greatest desirable width of hem, tuck, or plait. The base-plate is intended to lie fl'at upon the work-plate or bed of'the sewing-machine, with its length at right angles to the The upper plate, I), is thin enough to be flexible to permit the introduction of the cloth between the double and singlelips d and e, which are formed at the The upper plate, I), is made sufficientlynarrower than the lower 0ne, a to-make room for the sinooth-l'aced india;r ubber-covered rollerf,

the latter to the plate 11 and the former to the plate a, and which exert a downward pressure upon the roller. I r k is the gage plate, against which the folded edge of the hem,tuck, or plait runs in the sewing operation, and 'which'regulates the width of the hem, tuck, or plait. This plate is arranged in an upright positionpara-llel with the feed movement, and extends across the plates aand band rollerf to bear upon the work-plate orvhed of the sewing-machine, and a portion of it enters between the plates at and b. The saidplate i s firmly secured to arod, l, which is arranged at right angles to it, and fitted to slide through a fixed post, m, which is secured to the united portions of the plate'sa and b, and this post is fitted with a set-screw, it, to

fasten the rodl and secure the gage plate at a suitable distance from the ends of the plates a b and from the lineof stitching, according to the desired width of hem, tuck, or plait.

' In Fig. 3 there is shown in red outline a por-' tion of the work-plate A and a portion of the stationary arm B of a Wheeler 85 Wilson sewing-machine, illustrating the arrangement of myguide. pp are the slots through which the teeth of the feeder work; and the direction of the feed is indicated by anarrow.- q is the needle-hole. r is the screw-hole in the plate A, in which is inserted the screw for the attachment of what is k'uown as the small gage.

of that machine, and s-is the screw-hole in the arm for what isknown, as the large gage.

t is an arm attached rigidly to and standing out at a right angle from the connected portion 0 of the plates at b of my guide. and having provided in it a screw-hole, u,.for the reception of a screw screwingtiutothe hole 8 to secure the said arm t to the arm B. oisasmalt lug projecting downward from the plate a i i a position to enter the hole 1* (the screw being removed from the said hole) when the arm t is secured to B. as above described, for the purpose of steadying the plate a on-the work-plate A, and preventing the friction of the cloth passing between the plates a b from displacing the guide, which, owing to'the distance from the screw' at s u and. the leverage produced on the said screw, it would otherwise be very liableto do.

The operation of myguide is as follows: The

gage-plate k is adjusted at a snitable'distance backfroin the needle-hole q, according to the desired-width of the 119m,- tuck. or plait, and the cloth; having been doublet], is inserted between the plates at and b, with the edge'ofthe rom against the gage-plate k, and on the magated or toothed metallic roller,which has been employed in someguides arranged in a'sitnilar' manner, and, owing to the adhesive character ol'the said surface, prevents the cloth 'lrom running away from the gage-plate. -The lips d e on the plates on I) prevent any other. portions of the said plates from producing friction on the cloth, and the upper obliquely-arranged single lip, 6, matching in the groove in the lower correspondently'arranged double one, d, the said lips tend 'tolead the clot-h toward the guide, while the greater l'riction prodneed by the double lip counteracts the tendency-of the feeding device to move the lower thickness of the cloth faster than the upper one, and thereby producing a pnckering of the hem,rtnck,or

plait.

What Iclai n as my invention, and desire to secure by Letters Patent, is-

' The arrangement of an indie rubber roller,

in combination with the gage-plate k,snbstantially as herein specified. 3
